It's my first time with linux, so I really dont know if I should post here more pieces of information.
Ive already tried editing alsa-base.conf, however there weren't line with "options snd-hda-intel index=-2", which, accroding to topic with Alsa Upgrade Script, should have been included.

In Windows 7 everything works fine.

What should I do?

Re: No sound via HDMI, Asus UL80Vt

I don't think there's anything that has to do with hardware selection regarding this. I was almost going to post a similar topic asking for help but I found my solution -- it really very simple. Try if it works for you:

Click on the 'sound' button on the tray. Go to "Sound Preferences..." Go to the "Hardware" tab, and under "Profile" choose "HDMI output..." That's it!

I hope this works for you as it did for me. The thing is, it just didn't change automatically.

If using PulseAudio, add the following line to /etc/pulse/default.pa:
load-module module-alsa-sink device=hw:1,7
Change the device to hw:1,7 instead of hw:1,3

In addition, i add myself to the audio group as the guide suggested and reboot.
Start the alsamixer, press F6 to select the HDA nvidia, and press m to unmute S/PDIF 1 and voila ! My speakers are pumping the sound of joy!
